Safari users should know that there may be some software conflicts which can cause our "shopping cart" and "checkout" pages to malfunction, especially for a user who is logged in. Since the software problem is with Safari, and thus not something that I can fix, I suggest using another browser, if possible. The Safari issue should not occur if you are "logged off" and simply order as a "guest". Should you continue to have any problems, or simply prefer it, then you are welcome to order by telephone. Call toll free in the U.S. and Canada at (877) 535-8085. Others should call 1 (484) 602-5851. Please make sure your e-mail address is correct when ordering, in order that you will receive your acknowledgment and tracking number.
